So Ideally I'm looking at modifying this coop build from an 8'x10' coop that sits 2' off the ground to a 6'x8' that is 2' off the ground. This would make the run 8'x14'. So if I'm doing my coop math right I'd have plenty of room for 12 standard sized chickens. I'm in the mountains so the snow is sometimes deep and they may not want to come out which is fine.
